Description

SHORT TERM AEROSOL COMPOSITION FOR

MARKING OR DELIMITING ANY TYPE OF SURFACE FIELD OF THE INVENTION

The present invention is related to the industry of the manufacture of products used to landmark, to put up signs, to annotate or to delimit certain areas or distances in a short term or temporal way. More specifically, it relates to a composition for aerosol that allows to generate landmarks, signs or visible limits to long distances and that after a certain period of time disappears without leaving any type of spot or damage on the surface where it was applied.

BACKGROUND OF THE INVENTION

In diverse activities of the human being there is needed for use some type of landmark (s) on a surface to indicate some limit, some position, some sign or some distance, with the objective to carry out a certain action or task; in some cases the action is not performed in a repetitive or permanent way then, the landmarks must be of the of short term or temporal type, being in some cases of high importance that the above mentioned landmark does not leave a visible permanent sign of its use as soon as the action has finished and the landmark on the surface is already not needed.

There are some reasons for which the short term or temporal landmark must not leave any spot or track of its previous existence, for example, among others: prevent confusion in later actions, prevent alteration of the surface appearance, and prevent surface contamination. Likewise, due to the fact that the surfaces on which the landmarks are usually placed can be of different nature, (for example: concrete, natural grass, synthetic grass, wood, plastic, carpets, marble, metal, land, clay) the components constituting the landmark must not produce any adverse effect on the surface.

Additionally, the short term or temporal landmarks must remain visible during the time on which the desired task or action is carried out and not to hinder the accomplishment of it and by this way, it can be conducted in a proper way, the temporal marking thus keeping its integrity and visibility according to the requirements of the task or action, among others, the landmark should be visible to long distances during the period of time that it is needed, without exhibiting a gradual degradation during the development of the task or action, which could give place to confusions or that the desired goals or results cannot be reached.

In some cases, the desired task or action requires the use of temporal landmarks to be placed outdoors, where the landmark is exposed to different environmental conditions as wind, sun, dampness or rain that can affect the integrity of the landmark or the rate on which said landmark disappears, which causes that the action or task that needs the use of temporal landmarks cannot be conducted in a suitable way. The ease of generating the landmark is also an important desirable feature, since the action or task may require quickly or even simultaneously drafting of multiple landmarks of different forms and sizes in a determined frame of time. For example, in the case of tasks that require landmarks drafted on horizontal or inclines surfaces, as the floor, upon the prior art the person drafting must assume an uncomfortable position, close to the floor or inclined, and also requires a tool or accessory to draft the landmark, such marking is difficult to draft and requires a long time to be completed.

An alternative has been the use of aerosols with diverse compositions that allow generate short term or temporal marks, avoiding the use of any tool, nevertheless, the drafting or elaboration of the landmark does not eliminate the need of the user to adopt an uncomfortable position or to incline to draft the landmark. For example, patent applications MX 2012000968 (Pablo Cesar) and US 2004/0221766 Al, (Heine) describe the use of foam compositions to landmark the distance to which a player must be placed in a football match, for example at the moment to execute a free kick. Nevertheless, these compositions require that the user should apply the product to generate the landmark at a distance among 2.5 cm and 30 cm from the floor in order to landmark over it, which in turn makes difficult to draft landmarks of big sizes. For example, for drafting a long straight line landmark, it is necessary that the user adopts a flexed uncomfortable position and walks keeping said position. As result, the landmark is not drafted in a correct because it is discontinuous or it is not homogeneous.

In some cases, it is required to draft landmarks of different colors, in this respect the products existing in prior art do not fulfill the wished effect of not leaving any spot or track of its existence, due to the fact that after the temporal landmark disappear remains spots of the color of the landmark, in order to remove such spots, it is necessary to wash the surface or, in some cases, to conduct another treatment on the surface to remove the spot, for example through the use of organic solvents.

The use of products of the prior art is not comfortable for the users and also the landmarks becomes blurred to the distance. This due to the fact that the produced foam has neither the volume nor the suitable dimension. Neither the products of the prior art achieve the homogeneity of the drafted landmark for reaching its better aspect.

AIMS OF THE INVENTION

One of the aims of the invention is to obtain a composition for aerosol that allows to generate short term or temporal marks, which are visible to long distances and in addition, a lasting effect of between 1 and 10 minutes, yet in climatological adverse conditions as high temperature, wind or dampness when the landmark is drafted in outdoors, but that also being able to vanish when it is applied in interiors. Other aim of the present invention is to achieve the previous aim in such form that the landmark can be drafted from a height of 1 meter from a horizontal or sloping surface, obtaining a homogeneous and constant landmark, facilitating the composition application to the person who drafts the landmark in a such way that is not necessary to perform any flexion or to adopt any uncomfortable position to draft the landmark.

Another aim is to generate short term or temporal landmarks with diversity of colors to improve the visibility of the landmark in surfaces where the surface color impedes its visibility, or when its desired to take landmarks of different colors because of diverse motives such as to contrast landmarks from others or when specific meanings are assigned to landmarks of certain colors.

And all those aims and advantages that will become apparent by the reading of the present description in combination by the compositions indicated in the examples that form a part member of the present description.

In addition, optionally the composition can have a selected color due to the presence of at least a component that gives color and at least a pH regulator, which allows to generate color landmarks with the advantage of any remaining landmark or permanent spot of the color unlike the colored foams or aerosols known in the prior art which produces permanent spots which requires later washing of the surface or even, the need of using organic solvents.

The provision of color marking under the present invention results in a higher applicability to the invention, since it is possible to use it in those actions or tasks requiring the use of landmarks of different color or where some particular meaning is given to specific landmarks of certain colors, with the advantage that the invention prevents the formation of permanent or lasting marks, it is to say, that the color vanishes together with the landmark.

The component that provides color to the landmark has the property of changing from a specific color to colorless depending on the pH of the composition, which do not allow that any permanent colored landmarks remain. The composition is stable enough to prevent the change of color during the required time for the landmark to be visible and stable. Thus, the color will be kept stable up to 10 minutes as the drafted landmark in turn vanishing at the same time that the rest of the components.

The component that provides color to the foam is selected from the group comprising 2,4- dinitrophenol, (3,3-bis-(4-hidroxyphenyl)-l-(3H)- isobenzofuranone, 3,3-bis-(4-hydroxifenyl)ftalide), trinitrobenzoic acid, (3,3-bis (4-hydroxi- 5-isopropyl- o - toly 1) ftalide , m-nitrophenol, nitramine, o- cresolphtaleine , p -nitophenol , or a mixture thereof in a concentration of between 0.001 % and 2.0 % of the total weight of the composition.

In addition, the composition may contain at least a solvent that facilitates the incorporation of the component that provides color to the composition, is preferred the use of ketones, alcohols or mixtures thereof, even more preferred it is the use of ethyl alcohol, propanone or a mixture thereof and it is in a concentration of between 0.01 % and 5.0 % weight of the total weight of the composition.

The temporal landmark formed from the described composition is stable up to 10 minutes to a temperature of up to 50°C, in conditions of dampness of between 30 up to 100 % of relative dampness, for stable being understood that it preserves its volume, continuity of the landmark and therefore visibility to long distances, allowing to perform the action for which the landmark is needed. The modulation or adjustment of the component quantities allows to control the foam duration according to the needs and characteristics of the action or task for which the landmark is provided.

The composition object of this invention allows to generate landmarks with a volume of bubble controlled such that it is possible to visualize them from long distances and not to give place to any type of confusion regarding the position of the landmark.

The composition has the additional advantage of requiring a minor quantity of material, with respect to foams known in the prior art to generate a landmarks of similar dimensions, which results in the possibility of generating a bigger number of landmark units or requiring smaller containers to canning or packing the composition.

Another additional advantages provided by the composition of the present invention is not to need of the use of biocides since the composition is biological stable. Likewise, another advantage is that the composition of the invention is not flammable which eliminates the risk for the user who drafts the landmark and for those who use the landmarks; the inflammability of the composition was determined using the method ASTM D3065-01 "Standard test for flammability of aerosol products ", section 4 "flame projection test", the method indicated in the point 31.6 "Aerosol foam flammability test" of the document "Recommendations on the transport of dangerous goods, United Nations, 2009, Rev. 5" y the Directive 75/324/CEE from the European Union.

The composition is packed in a container for aerosol what facilitates its application, additionally the container and the valve associated to the activator has an ergonomic form to even more facilitate the application, the material of the container can be of steel, aluminum, plastic, PET or glass, the packages of aluminum are preferred due to its minor weight and higher resistance to the pressure.

The composition itself allows to generate temporal landmarks with each of the advantages and characteristics already mentioned, but additionally the effect is improved with respect to the height of application and the homogeneity of the landmark through the use of a discharge insert operatively associated with a valve activator for expelling aerosol, the discharge insert having an discharge orifice of a diameter of between 0.0254 cm to 0.1143 cm .
